Re: AT&T Note 3 Battery Life - Post Kit Kat Update

You can try going into Recovery mode, and clearing your cache there, it may or may not help. This won't erase any important data.

To wipe the cache partition, follow these steps:

Turn off the device.
Press and hold the following three buttons at the same time:

Volume Up key
Home key
Power key

When 'GALAXY Note 3' appears on the screen, let go of the Power key but continue to press and hold the Volume Up key and the Home key.
When the Android System Recovery screen appears, release the Volume Up and Home keys.
Press the Volume Down key to highlight 'wipe cache partition.'
Press the Power key to select and wipe the cache.
With 'reboot system now' highlighted, press the Power key to restart the device.

Reports are there's going to be a android 4.4.3 update roll out relatively soon to fix this problem, apparently it's something to do with a camera battery drain issue present in the current build of 4.4.2, why this wasn't caught before rolling it out to everyone I'll never know. I too am experiencing worse battery life and high android os usage.

Re: AT&T Note 3 Battery Life - Post Kit Kat Update

Same here for me... Battery life was less than normal and noticed at some points the phone was getting hot and then the next thing i know, the battery went from 30% to dead and the phone was off. Did a factory reset and everything has been great, i only wished Android had a back up set up like Apple due to having an app for my work that has to be reset every time this happens. I love my Note 3 but this is one one thing i really do miss the most.

Good concept but not so perfect execution. I used it yesterday to perform a "complete" backup before I did a complete wipe. I had some battery drain issues after installation of 4.4.2 so I tried Kies 3. The restore operation had taken 5 hours and completed 67 percent and then completely stopped. I am not sure what happened. So I ended up setting up the phone again from scratch and then used Kies 3 in stages, recovering messaging and phone data as well as some applications. I ended up just downloading most of them and used a backup I saved in Nova Launcher Prime to get my pages set back up. So in the end everything is back on my Note 3 and it is already noticeable that the battery drain problem I was experiencing is gone. It took longer than I liked but in the end I am happier with the battery life and it is at least comparable to when 4.3 was installed. I will continue to test and document with the screen shots I have recorded.

So I noticed by use of the app CPU spy that once I turn on my mobile data or Wi-Fi my phone will no longer go into deep sleep even when I turn them back off again. I turned off everything that could possibly be trying to sync as well as every app on my phone that can be turned off and nothing has helped. My phone is in a constant state of being awake no matter how long the screen is off. Its crushing my battery.
